Hi Generix, thanks for your insights on this and many other threads.
Indeed, while playing Valheim or doing benchmarks on Unigine Heaven GPU gets “capped” on 80W on my ASUS TUF, if nvidia-powerd is disabled.
As soon as I type systemctl start nvidia-powerd to start the service, more power is redirected to the GPU, confirming that if you need a power input higher than 80W, nvidia-powerd needs to be started. I was masking this service unit because asusctl was calling it and it was using an insane amount of CPU usage even with the GPU in idle state.
Other than that, I see no harm on keeping this service running since the problems with CPU usage spikes seem to be gone for good.
